CAR.

Specification of Letters Patent.

Patented Apr. 41, 1911.

Application filed December 29, 1909. Serial No. 535,413.

To all whom it may concern:

Be it known that LFRANCIS Xhlanoosar, a citizen of the United States,and a resident of the city of Jersey City, county of Hudson, and Stateof New Jersey. have invented new and useful Improvements in Cars, ofwhich the following is a specification.

The invention relates to cars and more particularly to the class ofpay-as-you-enter cars.

The primary object of the invention is the provision of a car of thischaracter in which the doors and steps thereof will simultaneously actunder the control of the conductor or motor-man. when standing at theirrespective ends of the car, so as to bring the doors and steps into aposition to permit the ingress and egress of passengers.

to and from the cars.

Another object of the invention is the provision of a car of thischaracter which is simple in construction, thoroughly reliable andetficient in operation and which may be manufactured at a minimumexpense.

In the accompanying drawings forming part of this specification isillustrated the preferred form of embodiment of the invention which toenable those skilled in the art to carry the invention into practicewill be set forth at length in the following description, while thenovelty of the invention will be brought out in the claims hereuntoappended. However it is to be understood that changes, variations andmodifications may be resorted to, such as come properly within the scopeof the appended claims, without departing from the spirit of theinvention or sacrificing any of its advantages.

For a more particular description of my invention, reference is to behad to the accompanying drawings forming part thereof, in which Figure 1is a sectional View of a portion of a car provided with my improvements.Fig. 2 is a sectional view taken at right angles to the sections shownin Fig. 1, and shows a number of the parts in elevation. Fig. 3 is asectional view of the construction shown in Fig. 1 showing the door openinstead of closed and the step shifted to correspond. Fig.4 is asectional view corresponding to Fi 2, except that the door and step areshown as in Fig. 3.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings by numerals, 1 designates a door which isnormally in closed position relative to the car, which is of theordinary well-known construction, the door being mounted to slidelongitudinally or transversely, as desired, but preferablylongitudinally, in the conventional manner. The door is supported by anysuitable means, (not shown). The floor or platform 2 of the car iscarried on a sill or platform knee 3 and is provided either on its endor its upper edge with suitable brackets 1 between 'which slide thesteps 5 so as to be under the car or platform 2 which closes theentrance and to protrude from under the floor 2 when the door 1 is notclosing the entrance. The mechanism for positively moving the door andstep in unison will now be described.

At any convenient point on the floor 2 is located an air cylinder 6provided with the conventional piston and piston rod 7 together withsuitable supply and exhaust pipes 8 and t) which are controlled byvalves (not shown), in the conventional manner. The piston rod 7 issupported near its outer end by a proper support 10 which is secured tothe floor 2, and through which the rod 7 slides with the usual movementin the direction of its axis but not. otherwise. The rod 7 is providedwith an enlargement 11 which carries a trunnion 12 that is adapted toengage with a suitable lever 13 which is slotted at 14 to receive thetrunnion 12 and fixed to the shaft 1!, on which it is fulcrumed. Theshaft 15 is journaled in a suitable bearing 16 fixed to the sill orplatform knee 3. The shaft 15 runs transversely of the car and is placedimmediately under a suitable opening 17 to receive the lever 13 as wellas a second lcvcrlS which is fixed to the shaft 15 and is connected atits upper end with a link 19 by a pivoted connection, which link 19 alsoruns to a bracket 20 secured to the door 1 so that the bracket 20 andlink 19 are pivotally connected. The link 19 and lever 18 are in thesame plane, as shown in Figs. 1 and 2, so that the door 1 may slide bythe lever 18 without interference.

The lower end of the lever 18 is pivotally connected to a bracket 21which can turn freely in the lower end of said lever but has no otherrelative movement thereto, and this bracket is pivotally connected to alink 22 that runs to a bell crank lever 23 fulcrumed at 24 and connectedat its outer end to a link 25 which is pivotally connected to a pointthat is near the center of the step 5 as by a suitable bracket 26. Theshorter arm of the bell crank lever 23 is connected with the link 22 andthe longer arm of the link 25 so that a limited movement of the link 22will cause a considerable movement of the step 5.

The operation of my improved device is as follows: Assuming the step tobe as shown in Figs. 1 and 2, the movable parts are shifted as shown inFigs. 3 and at by admitting air tlnough pipe 9 and permitting the pipe 8to be open to the atmosphere, as can easily be done by means of a valve,as is obvious, the air passing through the pipe 9 acts on the piston andforces the piston rod 7 to move toward the left thereby swinging thelevers 13 and 18 to correspond. The lever 18 throws the link 19 at theupper end and shifts the door, as shown. At its lower end the lever 18acts through the bracket 21 and throws the link 22 toward the right andmoves the bell crank lever 23 to correspond, and thereby slides with thestep 5 simultaneously with the opening of the door. To close the door,air is admitted through the pipe 8 and exhausted through the pipes 9 andthen the piston acts in the reverse direction and both the door and stepare moved in the opposite directions from those just described.

This construction just above described is particularly applicable to asliding door operating with a sliding step.

It is thought from the foregoing description that the construction andoperation of the invention will be clearly obvious, without requiring amore extended explanation and therefore the same has been omitted.

What is claimed is:

l. A step and means for mounting the same so that it will slide, aslidingly mounted door, and mechanism rigidly connecting said step anddoor for simultaneously sliding said step and moving said door.

2. In a device of the class described, a step, means for mounting thesame so that it can slide, a slidingly mounted door, links, levers, andother mechanism associated therewith for simultaneously moving said doorand sliding said step in fixed planes at an angle to each other.

3. In a device of the class described, a car door, means for mountingthe same so that it may slide, means for sliding said door, a step"adapted to slide ina plane at right angles to the plane in which thedoor slides, and means connected to said door moving means for slidingsaid step in unison with said door.

41'. In a device of the class described, a door, means for mounting thesame so that it may slide, a step mounted in a plane at right angles tothe plane of the door, and

means for sliding. said door and step simultaneously so that the stepwill be exposed when the door is open and concealed when the door isclosed.

5. In a device of the class described, a door, means for mounting thesame so that it may slide in a vertical plane, a step adapted to slidein a horizontal plane and adjacent sai ddoor and under thesame, apneumatic cylinder and a system of levers connected therewith for movingsaid door and step simultaneously.

6. In a device of the class described, a door, means for supporting thesame so that it may slide in a vertical plane, a step, means forsupporting the same so that it may slide ad acent to said door and 1n ahorizontal plane, a pneumatlc cylinder and a series of levers connectedtherewith and links for sliding said door and step simultaneously.

7. In a device of the class described, a door mounted to slide in avertical plane, means for supporting the same, a step mounted to slidein a horizontal plane, I

means for supporting the same, a pneumatic cylinder and a system oflevers and links connected with each other and to the cylinder andconnecting said door and step so that said door and step are positivelymoved in unison.

8. The combination'with a sliding door and step, of fluid controlledmeans having connections with said door and step to move one in a pathtransversely to the path of movement of the other.

9. The combination with a sliding door and step, of fluid operatedmechanism having connections with said door and step to actuate the samein unison so that one will move in a path transversely to the path ofmovement of the other.
